I've tried several times to install the product, and each time it gets to the Install Visual Studio Templates point, and just stays there. Last night I started the installation before I left for home, and logged back in 4 hours later. It was still at the same point. Any ideas?

You will want to load it again so that it will install itself in the VS2008 environment.  When you loaded SF, I am sure that you saw the option for both VS2005 and VS2008, you can install and run both versions side-by-side.  So when you load VS2008 just reload the SF install afterwards to update the VS2008 IDE.  Also, just FYI, when you install and uninstall StrataFrame, it leaves your license intact.  So if you have installed SF, and then uninstall and reload, you license information will be left alone and you will still be activated once you reload SF.
